Our Verdict
For most 2015-2020 Tahoe and Yukon owners, the CORSA Sport 3in Cat-Back is the best all-around exhaust — aggressive wide-open tone with zero highway drone.
The CORSA Sport pairs a deep, hand-on-the-throttle growl with patented Reflective Sound Cancellation (RSC) that keeps the cabin quiet at cruise. Want the same upgrade for half the price? The K&N 67-3082 is the best value pick. Running the 6.2L Denali? Skip to the CORSA Denali and Borla S-Type picks below.
Shop Our Top Pick →A cat-back exhaust is the single most popular upgrade for the 2015-2020 Chevy Tahoe and GMC Yukon, and for good reason: it wakes up the muted factory sound of the 5.3L and 6.2L EcoTec3 V8s, trims weight, and frees up a few honest horsepower — all without a tune or a trip to the dyno. The challenge is choosing between brands that sound completely different. At NLP Performance in Tampa, FL, the three names our Tahoe and Yukon customers ask for most are CORSA, Borla, and K&N. Below we compare five cat-back systems we stock, with real sound profiles, pipe specs, fitment notes, and pricing from $517 to $1,670, so you can match the right exhaust to your engine and your tolerance for drone.
How much horsepower does a cat-back exhaust add to a Tahoe or Yukon?
A cat-back exhaust typically adds 5 to 10 horsepower and a few lb-ft of torque to a 2015-2020 Tahoe or Yukon, with the bigger real-world gains being sound, throttle response, and a small weight reduction. The 5.3L EcoTec3 L83 V8 leaves the factory rated at 355 horsepower and 383 lb-ft of torque, while the available 6.2L EcoTec3 L86 makes 420 horsepower and 460 lb-ft. Because a cat-back system replaces only the piping and muffler behind the catalytic converters, it cannot dramatically change those numbers on its own — the catted mid-pipe and factory manifolds remain the primary flow restriction. What a cat-back does deliver is freer flow, a deeper exhaust note, and a system that often weighs less than the heavy stamped-steel factory unit. Pair it with a cold air intake and a tune and the gains stack; on their own, treat a cat-back as a sound and breathing upgrade first, and a modest power adder second.
CORSA Sport 3in single-side cat-back with twin 4in polished tips — our top overall pick.
What matters when choosing a Tahoe/Yukon cat-back exhaust?
The four factors that decide whether you love or regret a cat-back are sound level, interior drone, material quality, and exact fitment. Sound level ranges from mild (a slightly deeper version of stock) to aggressive (loud and unmistakable at wide-open throttle). Drone — that resonant boom around 1,800 to 2,200 rpm on the highway — is the number-one complaint on big SUVs, which is why CORSA built its Reflective Sound Cancellation (RSC) technology specifically to cancel it. Material matters for longevity: look for T-304 stainless steel, which resists rust far better than aluminized or 409 stainless on a daily-driven truck. Finally, confirm your engine and exit style: the 5.3L and 6.2L use different systems, and tip finish (polished vs. black) and exit location (single-side vs. split rear) change both looks and sound.
Sound level, from mildest to loudest
Brands label their sound tiers differently. Borla offers three: Touring is the mildest and most drone-free, S-Type is the popular aggressive middle, and ATAK is the loudest. CORSA splits its lineup into Touring (refined) and Sport (aggressive), with RSC keeping both drone-free in the cabin. K&N sits in the moderate range — clearly deeper and louder than stock, but civil enough for a long road trip. If your Tahoe is a family hauler, lean Touring or K&N; if it is a weekend statement, the CORSA Sport or Borla S-Type are the calls.

The 5 best cat-back exhausts for the 2015-2020 Tahoe & Yukon
1. CORSA Sport 3in Cat-Back — Best Overall (5.3L)
The CORSA Sport is our top overall pick because it delivers the aggressive note enthusiasts want without the highway drone that ruins long trips. It uses 3in mandrel-bent piping, a single-side exit with twin 4in polished tips, and CORSA's patented Reflective Sound Cancellation (RSC) technology to tune out resonance in the cabin. At wide-open throttle it has a deep, muscular bark; at a steady 70 mph it settles into a clean cruise. It is backed by a CORSA limited lifetime warranty.
What We Like
- + Aggressive wide-open tone with zero cabin drone (RSC)
- + 3in mandrel-bent stainless with twin 4in polished tips
- + Bolt-on fit, no cutting, limited lifetime warranty
Things to Consider
- – Premium price point
- – Built for the 5.3L; 6.2L owners should see the CORSA Denali kit
2. K&N 67-3082 Cat-Back — Best Value (5.3L)
The K&N 67-3082 is the best value cat-back for the 2015-2020 Tahoe and Yukon 5.3L, delivering a noticeably deeper tone for roughly a third of the price of a premium system. It is engineered for a fast, clean install — typically under 30 minutes using factory mounting points with no cutting — and maintains clearance to critical chassis systems. The stainless construction and polished tip look factory-plus rather than race-car loud, making it ideal for owners who want more sound without commitment to an aggressive drone. Note: this kit sells quickly and may show as backordered; contact our Tampa team for the next restock date.
What We Like
- + Lowest price of any kit here by a wide margin
- + Installs in under 30 minutes on factory mounts, no cutting
- + Civil, deep tone that is road-trip friendly
Things to Consider
- – Not as loud as the CORSA Sport or Borla S-Type
- – High demand means it is often on backorder
The K&N 67-3082 installs in under 30 minutes using factory mounting points.
3. Borla Touring Cat-Back — Best for Quiet Daily Driving (5.3L)
The Borla Touring is the right call for owners who want a richer tone but refuse to live with drone on the commute. Touring is the mildest of Borla's three sound levels, sitting below S-Type and ATAK, and it is the most cabin-friendly cat-back in this guide alongside the CORSA systems. It runs 2.75in and 2.25in piping into a dual, same-side exit with 4in tips, is built from T-304 stainless steel, and carries Borla's industry-leading Million-Mile warranty. You get a deeper, more confident note at acceleration and a near-stock quiet at cruise.
What We Like
- + Quietest, most drone-free option here for daily driving
- + T-304 stainless with a Million-Mile warranty
- + Refined tone that will not wake the neighborhood
Things to Consider
- – Too subtle if you want a head-turning sound
- – Same-side dual exit is not for everyone's look
4. CORSA Denali 6.2L Cat-Back — Best for the 6.2L Yukon Denali
If you run the 420-horsepower 6.2L L86 in a Yukon Denali, the CORSA Denali cat-back is purpose-built for your engine and exhaust routing. It uses a single-side exit with polished tips and the same RSC technology that makes CORSA the drone-free benchmark, so the larger 6.2L gets a deeper, more authoritative voice without a resonant boom at highway speed. It is the natural counterpart to our top-pick Sport system for owners with the bigger motor, and it is backed by CORSA's limited lifetime warranty.
5. Borla S-Type Cat-Back — Loudest Street Sound (6.2L)
The Borla S-Type is the most aggressive cat-back in this guide and the pick for 6.2L Yukon Denali and Escalade owners who want their truck heard. S-Type is Borla's popular middle sound tier — louder and more aggressive than Touring, just below the range-topping ATAK. It features a split side exit, T-304 stainless construction, and the same Million-Mile warranty. Be aware that some owners report mild drone in the 1,800 rpm range; if a perfectly quiet cabin is non-negotiable, choose the CORSA Denali instead.
What We Like
- + Loudest, most aggressive sound for the 6.2L
- + T-304 stainless and a Million-Mile warranty
- + Aggressive split side-exit look
Things to Consider
- – Some owners report mild drone near 1,800 rpm
- – May be too loud for a quiet family hauler
Key Specifications — CORSA Sport (Top Pick)
How hard is it to install a cat-back exhaust?
Installing a cat-back exhaust on a 2015-2020 Tahoe or Yukon is a bolt-on job that most DIYers complete in 30 to 90 minutes with hand tools. Every system in this guide reuses the factory hangers and mounting points, so no welding or cutting is required — the K&N 67-3082 is specifically engineered for a sub-30-minute install. You will need a floor jack and stands, penetrating oil for the factory clamps, and an extra set of hands to support the system during alignment. Let the exhaust cool fully before starting, spray the rubber isolators with lubricant so the hangers slide off cleanly, and snug all clamps before final-torquing to keep the tips evenly spaced. Prefer to leave it to a professional? Our team at NLP Performance in Tampa, FL can source and install any of these systems and confirm exact fitment for your VIN.

Frequently Asked Questions
What is the best cat-back exhaust for a 2015-2020 Chevy Tahoe?
The best overall cat-back exhaust for a 2015-2020 Chevy Tahoe is the CORSA Sport 3in system ($1,669.94), which combines an aggressive wide-open tone with patented Reflective Sound Cancellation (RSC) that eliminates highway drone. For shoppers on a budget, the K&N 67-3082 ($517.04) is the best value, and for the quietest daily-driver setup, the Borla Touring ($1,477.99) is the top choice.
How much horsepower does a cat-back exhaust add to a Tahoe or Yukon?
A cat-back exhaust typically adds 5 to 10 horsepower and a few lb-ft of torque to a 2015-2020 Tahoe or Yukon 5.3L or 6.2L V8. Because it replaces only the piping behind the catalytic converters, the main benefits are a deeper sound, slightly better throttle response, and reduced weight rather than a large power jump. For bigger gains, pair the cat-back with a cold air intake and an ECU tune.
Will a cat-back exhaust cause interior drone on the highway?
It depends on the brand. CORSA systems use Reflective Sound Cancellation (RSC) technology to eliminate the resonant boom most owners call drone, and the Borla Touring is also engineered to be drone-free. More aggressive systems like the Borla S-Type can produce mild drone around 1,800 rpm. If a quiet cabin at cruise is a priority, choose a CORSA Sport, CORSA Denali, or Borla Touring system.
Does a cat-back exhaust fit both the 5.3L and 6.2L engines?
No — the 5.3L and 6.2L use different cat-back systems because of their exhaust routing, so you must match the kit to your engine. The CORSA Sport, K&N 67-3082, and Borla Touring in this guide fit the 5.3L V8, while the CORSA Denali and Borla S-Type are sized for the 6.2L Yukon Denali and Escalade. Always confirm fitment by engine and model year before ordering.
Do I need a tune after installing a cat-back exhaust?
No, a cat-back exhaust does not require a tune. It mounts behind the catalytic converters and does not change any sensor readings, so your Tahoe or Yukon runs normally with no check-engine light. A tune is only needed for larger modifications such as headers, a supercharger, or a camshaft. The cat-back is a true bolt-on that works with the factory ECU calibration.
Is a cat-back exhaust street legal in the United States?
Yes, a cat-back exhaust is street legal in all 50 states, including California, because it does not alter or remove the catalytic converters or any emissions equipment. Only systems that replace the converters (off-road or high-flow cat pipes) face emissions restrictions. The CORSA, Borla, and K&N cat-back kits in this guide retain the factory cats and pass standard emissions inspection.
